hars 29; and while the construction which comprises compound anvilblocl'is, consisting of upper parts 24 :resting on the upper innersupports 19, and lower parts interposed between the upper an d lowerinner supports 19, these anvil s or blocks being held in flanged collarsrigidly secured to the said inner sup- 19 oy bolts 2li passing throughthe es of said collars and through clamping l loo rs 27 and 28 betweenwhich are gripped transverse supporting cross bars 29 which sustain andbrace the inner supports 19, and which, to a considerable extent,receive the ercussive shocks imparted to the anvil blocks by thevibrating hammers 30. These hammers 30 are preferably in the form oflhell-crank levers, and are pivoted in brackets B1 sustained on the cover32 ot those arator, said cover being preferably provide with a hingedjoint 33 at its upper end so that v,it may he lifted, when desired, aswhen the removably mounted screens are to be inserted or taken out. Thecover 32 supports roig shafts 34 provided with driving pul- 35 andcarrying at their inner ends rol' arms 36 provided with rollers 37 tothe upturned ortions of `ie oeil-crank hammers BO'r'or t e purpose tl o'lifting the same, said hammers falling by gravity on the anvil blocks 24when their upturned arms escape from theA operating rollers 3?.

The hammer-operating arms are covered by hinged hoods 38 which preventescape of dust through the cover 32, but which may be lifted when accessto the .said arms is necessary. It will thus be understood that anviloloclrs or hammer posts do not pass tirough the screens, as in theformer conf "",ruetion referred to, and as the vibrating hammers 3Q aremounted m the screening chamber no openings inthe top or cover saidchamber, for the passage of hammer posts, are'required. In other Wordslarring devices are inclosed in the screencnamber in the presentimproved sepa- 'lhe cover 32 is supplemented at its uwer end by whichcloses the top of the lower part of the chamber of the separator. Accessto the screening chamber from the back of the separator is afforded by adoor 40 which is hinged at its top end to the frame of the separator.

From the foregoing it will he'understood t ist the screens are supportedby the longitudinal side bars 18 and the longitudinal inner bars 19, thelatter being in turngsustained by the upper and lower transversecscreens are thus, in se. unyielding. in t they do not rest ogs, thq fare so supported that they ly jarred, in the screenthe impact of the'hain- .by .securing a very e lthereof to the lowerscreens,

a smaller hinged cover mers 30 against the compound anvil blockscomprising the parts 24 and 25. In other words, the screen supportsthemselves are hammerlvibrated by the impact of the hammers.

Owing to the fact that the framed screens or screen sections rest attheir inner edges on the resilient or elastic inclined longitudinalsupports 19 which are between two adjacent framed screens and towhichthe anvil blocks are secured,y and which elastic longitudinal supportsare sustained between their ends by resilient or elastic transverse bars29, the percussive impact of the hammers on the anvil blocks, which arereferably disposed in the vertical plane of oth of said longitudinal andtransverse bars, -will agitato the inner edges of said screens mostviolently, or will impart maximum vibrations to the inner ,edges of thescreens, the outer edges'ofwhich. rest on the rigid ports 18 on theseparator frame. This action results in such side wa'ves of movement ofthe screen clothing as will cause the mafterialA traveling driven'moreor less erosswise of the screens; and thus the material will traveldownward in a more or less zi zag course, there? ective` and rapidscreening operation. I

The lower parts 25 of the compound anvils not only serve to communicatethe impact of the hammers from the upper parts but also serve as spacingblocks for the inner supports 19, these, supports 19' and transversebars 29 constituting, when the machine is in operation, what may betermed a hammer-'operated vibrating frame for communicating jarringmovements to the screens.

Havingl thus described my invention I claim and desire to secure byLetters Patent:- y

1. In a separator, the combination with removable, inclined framedscreens comprising wire mesh clothing, of one or more resilientlongitudinal supports for said screens, and means for percussivelyjarring said supports.

2. Inj a separator, the combination with ai plurality of resilientlongitudinal screen supports, one above the other, of resilienttransverse bars sustainin said longitudinal bars, and inclined framescreens removably mounted on said longitudinal supports and comprisingwire mesh clothing, and means for percussively jarring said resilientsupports.

3. In a separator, the combination with a plurality oi' inclinedresilient longitudinal supports, one abovey the other, of screen framesremovably mounted on said supports and provided vwith wire mesh clothornon-resilient longitudinal sup-A down the screens to be' -mounted onsaid supports, anvil blocks ing, means tor peroussively jarring saidresilient supports, and means for removably attaching said screenJtrames to said supports.
